Sibling and Twin Relationships Survey
The purpose of this research is to learn more about twin and sibling relationships and their impact on relationship development.
You must have a sibling and be 18 years of age or older to participate in this study.
If you agree to be in this research, we will ask you to spend approximately 20 minutes filling out a series of questionnaires. If you are unable to complete each set of questions in one sitting, you will have the opportunity to create a private user name and password so that you can return to this site at another time.
If you volunteer to be in this study, you may withdraw at any time without consequences of any kind. You may also refuse to answer any questions you don't want to answer and still remain in the study.
There are no anticipated risks to you for participating in this research. As a benefit of participating in this research, you may learn more about your relationships, and you will be helping the field of psychology by providing us with valuable data on these relationships.
The researchers conducting this study are Chris Fraley, PhD and Caroline Tancredy, M.A. You may ask any questions you have before you begin the study. If you have questions now or later, you may contact Caroline Tancredy by e-mail at firstname.lastname@example.org, or by phone at our research office at (773) 235-3016.
For New Participants
If you have not participated in this study before, you will need to create a user name and password below. Try to make your user name unique-- something that no one else would choose. Please limit your user name and password to 10 characters or less and please do not use spaces. Also, be sure to write it down; you will need to enter it each time you choose to work on the study. The user name and password will be case sensitive (i.e., lowercase vs. uppercase letters will be treated differently).
For Returning Participants
If you already have a user name and password and would like to continue the study, please enter your user name and password below. Please keep in mind that the user name and password are case sensitive (i.e., lowercase vs. uppercase letters are different).
